KUNIT_ASSERT..._ERR_OR_NULL(9)

💖 KUNIT_ASSERT..._ERR_OR_NULL(9) 💖

Hey bestie, welcome to the Kernel API Manual page for KUNIT_ASSERT..._ERR_OR_NULL(9) — aka the page all about KUNIT_ASSERT_NOT_ERR_OR_NULL. Pointer vibe check incoming 💅✨

---

✨ NAME ✨

KUNIT_ASSERT_NOT_ERR_OR_NULL — an assertion that @ptr is not null and not err. 💖

---

🎀 SYNOPSIS 🎀

KUNIT_ASSERT_NOT_ERR_OR_NULL (test , ptr );

---

💅 ARGUMENTS 💅

• test — the test context object.
• ptr — an arbitrary pointer.

---

🦋 DESCRIPTION 🦋

Okay so this one sets an assertion that the value that ptr evaluates to is not null and not an errno stored in a pointer. No cap, that's the whole vibe check 🫶

It's literally the same as KUNIT_EXPECT_NOT_ERR_OR_NULL, except — plot twist — it causes an assertion failure (see KUNIT_ASSERT_TRUE) when the assertion is not met 😭🔥
